North Korea on Wednesday harshly condemned South Korean President Moon Jae-in again for his latest remarks on unwavering sanctions on North Korea's nuclear development, irrespective of inter-Korean dialogue, calling them "stupid and nasty words."

During a New Year press conference on Jan. 10, Moon expressed thanks to US President Donald Trump, saying that the inter-Korean talks that opened the previous day might have been an effect of US-led international sanctions and pressure on the North for its nuclear development. He also said Seoul will continue to keep pace with pressure and sanctions by the international community until the North Korean nuclear issue is resolved. The minister-level talks were held to discuss the North's participation in the upcoming Winter Olympics in the South Korean alpine town of PyeongChang.

"We can never pass over the South Korean leader's remarks that offended us and openly laid his vicious mind bare at a time when the two Koreas just took their first step to improve their relations," the Rodong Sinmun, the North's ruling Workers' Party daily newspaper, said in a commentary titled, "Inappropriate Behavior That Pours Cold Water on Dialogue."
